Step-by-step explanation:
this question is kinda tricky
Answer:
Step-by-step explanation:
Let
![x=1.323232...](https://tex.z-dn.net/?f=x%3D1.323232...)
Multiply x by a power of
, one that keeps the decimal part of the number the same:
Subtract
from
The repeating decimals should cancel out
solve for x
Divide by
both sides
Hi there!
F =
![\dfrac {km}{r^2}](https://tex.z-dn.net/?f=%5Cdfrac%20%7Bkm%7D%7Br%5E2%7D)
To solve for ' r '
Follow these steps :-
• Multiply r² both sides -
F × r² =
![\dfrac {km}{r^2}](https://tex.z-dn.net/?f=%5Cdfrac%20%7Bkm%7D%7Br%5E2%7D)
× r²
F × r² = km
• Divide F from both sides -
r² =
![\dfrac {km}{F}](https://tex.z-dn.net/?f=%5Cdfrac%20%7Bkm%7D%7BF%7D)
r =
![\sqrt{ km/F }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20km%2FF%20%7D%20)
Hence,
Option D. r =
![\sqrt{ km/F }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20km%2FF%20%7D%20)
is Correct
~ Hope it helps!
Step 1: -3(x+2y=3)
Step 2: -3x-6y=-9
Step 3: 3x cancels out with -3x
Step 4: add 2y and -2y, and add 3 and 5
Step 5: the answer is NO SOLUTION or INFINITE SOLUTION
